SPECIFICATION forming part of Letters Batent No. 494,010, dated March21, 1893. Application filed eptember 22, 1 89 2. Serial No. 446,614. (Nomodel) To all whom it may concern:

Be it known that I, HARRY MERRILL LIT- TLE, of Rivera, in the county ofLos Angeles and State of California, have invented certain new anduseful Improvements in Cultivators; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in cultivators and its object is tofurnish a cultivator which has a harrow bar attached, and in which theblades of the cultivator as well as the harrow teeth may be quickly andevenly raised from contact with the ground.

My invention also consists of the novel combination, construction andarrangement of parts hereinafter fully specified and pointed out in theclaims.

In the drawings, Figure 1 is a perspective of my cultivator, and Fig. 2is a side elevation of the blade, showing the mode of connecting samewith the beam.

A is a metal U shaped frame, the open ends of which are connected by awooden cross piece B, which carries the support or bearings C for theshaft D. To the forward part of the frame A are hinged the beams E andF, which extend backward over the cross-piece B, and carry the shares Gand H respectively. The beams E and F are connected by means of pivotedconnecting links I to rearwardly extending arm J of the shaft D.

On the right hand of the seat K and secured to the shaft D is theupwardly extending lever L, and means for holding the lever in thedesired position.

Extending backward and downward from the axle of the wheels M are thepivoted supports N to the rear ends of which is pivoted the cross-beamO, which carries the harrow teeth P. Extending upward from the beam 0 isthe arm Q, which is connected with the lever R, which is pivoted to thebeam 13, by the connecting links S. The lever R is situated on the lefthand of the seat K and is held in the desired position by means of thepivoted serrated piece T, the serrations of which are adapted to fit theshaft D.

To the forward part of the frame A is hinged the pole U, which is bracedto the frame by means of the braces V.

To the rear of the pole just forward of the frame A is hinged the beamW, which extends backward over the cross-beam B, and is connected to aprojecting arm on the shaft D, by means of a connecting rod similar toI, and to the beam W is bolted the beam X of the share Y.

Bolted to the frame A are .L pieces Z, one on either side of the pole Uand to the outwardly projecting portions of the L pieces Z are pivotedconnecting links Z, the other ends of which are pivoted to the beam W.

To balance the weight of the beams and plow-shares I have used springs(a) one at each end of the shaft D and connected to the shafts D and thesupports 0.

In Fig. 2 I have shown the manner of connecting the share Y to the beamX, which consists of having the upper bolt hole 3 rectangular and alsoone of the holes 4 through which the bolt which secures the blade of theshare Y to the share, rectangular. By this means the share and blade canbe tilted at any desired angle with the beam X.

The construction and arrangement of the several parts of my cultivatorbeing thus made known, the operation and the advantages of the samewill, it is thought, be readily understood. A

The object of the connections between the beam W and frame A and havingthe pole U hinged to the frame A and beam W, is to allow the shares toremain in a plane parallel to the ground when they are raised, or inother words' to prevent them from dipping when raised from the ground.

When it is desired to cultivate the ground, the levers L and R are swungbackward until the shares and harrow teeth enter the ground to therequired depth, and the machine is then drawn forward over the ground.

It will be readily seen from the foregoing description that I haveprovided a very simple and eifective cultivator, which willhave a lightdraft and by the use of which the entire surface of the ground will bethoroughly cultivated and pulverized.

Having thus described my invention, what I claim,'and desire to secureby Letters Patent, 1s-

1. In a cultivator, the combination of pole U, frame A, cross-piece B,harrow bar 0, shaft D, beams E and E, which are hinged to the frame A,beam W hinged or pivoted to'pole U, and also having connecting links toframe A, said pole U beinghinged tothe frame A, in combination withsprings (a) and shares G, Yand H, and means for raising and lowering theshares G, Y and H, substantially as and for the purpose set forth.

2. In a cultivator, the frame A, pole U, said pole being hinged to saidframe in combination with beam W carrying a plow share, said share beingconnected to said beam by means of bolts, which passthrough rectangularslots in said beam, said beam being hinged or pivoted to said pole U andalso bearing pivoted connecting links which connect said beam to saidframe A, and means for raising or lowering the rear end of said beam,substantially as and for the purpose setforth.

3. In a cultivator, the frame A, pole U hinged to said frame, beams E, Wand F, said beams E and F being hinged to said frame and beam W beinghinged to said pole and connected to said frame by means of pivotedconnecting links, shaft D having arms which are connected to said beamsE, W and F by means of connecting rods, harrow bar 0 bearing harrowteeth P, said harrow bar being pivotally supported by means of supportsN, said harrow bar having arm Q, which is connected to lever R by meansof rod S, and 1ever L adapted to raise or lower the beams E,

W and F and shares G, Yand H, substantially as and for the purpose setforth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

HARRY MERRILL LITTLE.
